Hi everyone!

I’m a software developer, and I use ChatGPT extensively for programming and technical projects.

One issue I’ve noticed is **context window saturation**.

From my experience, I’ve been using approximately **250,000 tokens** as a reference limit. However, ChatGPT doesn’t provide a clear warning when a conversation is approaching its context limit.

Does anyone else find this frustrating?

When you’re working on complex projects, losing access to important parts of an earlier conversation without a clear warning can be a real problem.

**Here’s a small tip for developers:**

You can open Chrome Developer Tools (F12 → Network) and inspect the network requests ChatGPT uses to retrieve conversation history.

By examining these requests and using a tokenizer, you can build your own Chrome extension to automatically count the tokens in a conversation and receive warnings before reaching a chosen threshold.

**I actually created my own Chrome extension for this purpose.**

It monitors the conversation’s token count automatically and warns me when the historical token count approaches my reference limit, giving me time to save important information before continuing in a new chat.

Of course, historical token counts are not necessarily identical to the model’s actual active context usage, but they provide a useful indicator.

I’m not trying to promote anything. I simply wanted to share this idea with other developers who use ChatGPT as much as I do.

\*\*If anyone is interested or curious about the extension I’ve built, feel free to ask

Has anyone else encountered this problem or developed a similar solution?
